## Summary description

Tele Vue Ethos 13mm eyepiece is a wide-field astronomical eyepiece with 13 mm focal length and dual 2"/1.25" barrel compatibility. Designed for visual observation, it provides a large apparent field of view for deep-sky and planetary viewing. Suitable for telescopes supporting 2" and 1.25" focusers, it offers comfortable eye relief and precise mechanical fit for serious observers.

## Long description

The Tele Vue Ethos 13mm is a premium wide-field astronomical eyepiece engineered to deliver an immersive viewing experience for both deep-sky and planetary observation. Featuring a 13 mm focal length and a sophisticated optical design, this eyepiece provides a expansive apparent field of view that allows observers to take in vast regions of the night sky with exceptional clarity and contrast. Its dual-barrel design ensures compatibility with both 2-inch and 1.25-inch telescope focusers, making it a versatile addition to any high-end optical setup.
Advantages
This eyepiece stands out due to its advanced optical construction which minimizes aberrations and ensures edge-to-edge sharpness across the entire field of view. The high-quality glass elements are precision-polished and multi-coated to maximize light transmission, resulting in bright, high-contrast images of faint nebulae, star clusters, and planetary details. The mechanical build is robust and reliable, providing a secure fit in the focuser while maintaining precise alignment for optimal performance during long observation sessions.
Suitable for
Deep-sky observation of nebulae and galaxies
Detailed planetary and lunar viewing
Wide-field star hopping and constellation study
Use with telescopes equipped with 2-inch or 1.25-inch focusers
When it may not be suitable
This eyepiece may not be the ideal choice for users with very small or entry-level telescopes that cannot support the weight or the wide field of view provided by premium optics. Additionally, observers who prefer a very narrow field of view for specific high-magnification planetary work might find the expansive nature of this eyepiece less focused than dedicated planetary orthoscopic designs.
Key specifications
Focal length: 13 mm
Barrel size: Dual 2-inch and 1.25-inch compatibility
Optical design: Wide-field
Application: Deep-sky and planetary observation
How to use
To use the Tele Vue Ethos 13mm, insert the eyepiece into your telescope's focuser. If using a 2-inch focuser, ensure the barrel is fully seated and tightened with the locking screw. For 1.25-inch focusers, utilize the appropriate adapter section of the barrel. Once secured, adjust the telescope's focus knob slowly until the image appears sharp. Because of the wide apparent field of view, it is recommended to center your target carefully to take full advantage of the immersive perspective.
What to consider before purchase
Ensure your telescope mount can handle the weight of high-quality wide-field eyepieces
Verify that your telescope's focal ratio is compatible with wide-field designs for optimal edge correction
Consider the physical size of the eyepiece when planning for storage and transport
Usage recommendations
Regularly clean the optical surfaces using a high-quality lens cleaning kit to maintain image clarity. Always store the eyepiece in a dry, dust-free environment with the provided caps securely in place when not in use to protect the coatings.
